This application is a continuation of U.S. application Ser. No. 17/179,162 filed Feb. 18, 2021, entitled CONTAINER FOR FOOD PROCESSING SYSTEM, the contents of which are incorporated herein by reference in their entirety for all purposes.
Embodiments of the present disclosure relate to a blender, and more particularly to a container of a blender configured to receive one or more food items therein.
Blenders are commonly used to process a plurality of different food products, including liquids, solids, semi-solids, gels and the like. It is well-known that blenders are useful devices for blending, cutting, and dicing food products in a wide variety of commercial settings, including home kitchen use, professional restaurant or food services use, and large-scale industrial use. They offer a convenient alternative to chopping or dicing by hand, and often come with a range of operational settings and modes adapted to provide specific types or amounts of food processing, e.g., as catered to particular food products.
When blending thick or frozen ingredients, the ingredients will often stick to the sidewalls of the container, resulting in areas of unprocessed food. This accumulation at the sidewalls of the container, also known as cavitation, occurs because the ingredients are too thick to form a vortex within the container which typically facilitates movement of the ingredients towards a food processing blade during a blending operation.
According to an embodiment, an attachment for use with a food processing system includes a container body having a sidewall, a first end configured to be mounted to a food processing base, and a second end remote of said first end. The first end is open and the second end is at least partially open. A chamber is defined by said container body and an agitating member is receivable at the first end.

In such embodiments, the attachment 30 further includes a first agitating member 42, such as a cutting assembly, configured to removably couple to the first open end 34 of the container 32 to seal the processing chamber 40. In the illustrated, non-limiting embodiment, the cutting assembly 42 includes a body 44 and one or more blades 46 rotatable about an axis X relative to the body 44. When the cutting assembly 42 is connected to the end 34 of the container 32, the first agitating member including the least one blade 46 is disposed within the processing chamber 40 of the container 32. The container 32 and the cutting assembly 42 may be threadably coupled together; however, it should be understood that other mechanisms for removably connecting the container 32 and the cutting assembly 42, such as a bayonet connection or a clip for example, are also contemplated herein.
In each of the various attachment configurations, the cutting assembly 42 is configured to operably couple to the food processing base 22 of the food processing system 20. A driven coupler 48 (see
In embodiments where the attachment 30 includes an inverted container 32, the attachment 30 may include one or more contact members 49 (
The contact members 49 of the attachment 30 are configured to cooperate with a mounting area 50 (see
With continued reference to
Any suitable second agitating member 60 is contemplated herein. In the illustrated, non-limiting embodiments, the second agitating member 60 includes a base 64 mountable about the shaft 62 and having at least one prong or paddle 66 extending at a non-parallel angle from the base 64, such as towards the open end 34 of the container 32. The base 64 and the one or more paddles 66 may be integrally formed as a unitary structure, or alternatively, may be multiple components connected together to form the second agitating member 60. Further, the base 64 and/or the paddles 66 may be integrally formed with the shaft 62, or alternatively, may be removably mounted thereto. Although the second agitating member 60 shown in
Examples of various configurations of a second agitating member 60 are illustrated in
A clearance defined between the one or more paddles 66 of the second agitating member 60 and the sidewall 38 of the container 32 may be selected to prevent large food particles from becoming trapped between the second agitating member 60 and the sidewall 38. In an embodiment, at least a portion of one of the paddles 66 has an angle generally complementary to the sidewall 38 of the container 32. As a result, when the second agitating member 60 is positioned within the container 32, the paddle 66 and the sidewall 38 may be parallel to one another, with only a minimal clearance defined there between. Further, by designing one or more of the paddles 66 to match a contour of the adjacent portion of the container 32, the second agitating member 60 may only be insertable into the processing chamber 40 when in a specific orientation. As a result, incorrect installation of the second agitating member 60 may be avoided. However, in other embodiments, at least a portion of one of the paddles 66 may be arranged at a non-parallel angle relative to the interior of the sidewall 38 of the container 32. A non-parallel orientation may be used be used to eject food and limit or prevent scraping of the interior of the sidewall 38.
In an embodiment, best shown in
To retain the second agitating member 60 at a desired position within the chamber 40, a mounting member 71 may be connected to a portion of the container 32, such as an exterior surface of the second end 36 for example. The mounting member 71 includes a through hole (not shown) configured to receive a portion of the shaft 62. When coupled to the container 32, the mounting member 71 is rigidly affixed to the body of the container 32. Accordingly, the second agitating member 60 is configured to rotate about the axis Y relative to the stationary mounting member 71. The mounting member 71 may be connected to the container body via any suitable means, such as via one or more fasteners for example.
In an embodiment, the second agitating member 60 is manually operated via an input from a user. As shown, a manual input device 72, such as a dial or cap for example, is operably coupled to the second agitating member 60 and/or the shaft 62 about which the second agitating member 60 is mounted. The manual input device 72 is connected to the shaft 62 at a location external to the container 32. In the non-limiting embodiments illustrated in
In an embodiment, illustrated in
The manual input device 72 may be directly connected to the second agitating member 60 such that a single turn of the manual input device 72 results in a corresponding single turn of the second agitating member 60. However, embodiments where the manual input device 72 is indirectly coupled to the second agitating member 60, such as via a gearing mechanism, are also within the scope of the disclosure. In such embodiments, a single turn of the manual input device 72 may result in several turns of the second agitating member, or alternatively, less than one turn of the second agitating member 60.
In an embodiment, the second agitating member 60 does not move during operation of the cutting assembly 42. To prevent undesired movement of the second agitating member 60 relative to the container 32 during operation of the cutting assembly 42, the attachment 30 may further include a lock 76 operably coupled to the second agitating member 60. In an embodiment, the lock 76 includes a ratchet or a one-way clutch device associated with the shaft 62 and/or the manual input device 72. In such embodiments, the ratchet 76 may be a separate device mounted to the second end of the container 32, such as between the container 32 and the manual input device 72, as shown in
In another embodiment, illustrated in
The second agitating member 60 may be permanently affixed to the container 32. However, in an embodiment, the second agitating member 60 is separable from the container 32, the mounting member 71, and/or the manual input device 72, such as to facilitate cleaning thereof. With reference now to
With reference to
In yet another embodiment, the processing assembly may be removably connected to the manual input device 72 via a snap fit or spring clip type of connection. As shown in
To separate the second agitating member 60 from the resilient members 100, a force applied to the second agitating member 60 must be sufficient to push the resilient members 100 outwardly, out of engagement with grooves 98. In another embodiment, shown in
With reference now to
As shown, the tamper 160 has a generally cylindrical body 206 having a diameter smaller than the diameter of the opening 204; however, it should be understood that a body 206 having any cross-sectional shape is within the scope of the disclosure. A radially outwardly extending flange 208 is connected to the cylindrical body 206 adjacent a first end 210 thereof. The diameter of the flange 208 is greater than the opening 204 to restrict the end 210 of the tamper 160 from falling through the opening 204 into the chamber 140. As a result, in use, a portion of the tamper 160 is positioned within the chamber of the container 132 and a portion of the tamper 160 remains adjacent an exterior of the container 132. In any embodiment including a tamper 160, the cylindrical body 206 of the tamper 160 arranged within the chamber 140 is operable as an agitating member to stir or move the one or more food items arranged within the chamber 140. The agitation performed by movement of the body 206 within the chamber 140 occurs in response to a manual input applied to the end 210 thereof.
With reference now to
In the illustrated, non-limiting embodiment, another agitating member 310 is positioned in overlapping arrangement with a portion of the cutting assembly 242. The agitating member 310 includes a body 312 having a generally hollow interior (not shown) within which the one or more blades 246 of the cutting assembly 242 are receivable (see
A contour of the exterior of the agitating member 310 may be shaped to perform a desired processing operation. In an embodiment, the agitating member 310 is operable to perform a mixing operation rather than a cutting or chopping operation. As best shown in
A single-serve or personal blending container including an agitating member 60, 160 or 210 as illustrated and described herein allows for the production of a thick, consistent culinary output, while minimizing excessive cavitation. Further, minimal input is required from a consumer to operate the processing assembly to encourage the flow of ingredients back towards the blades performing the blending operation.
With reference now to
The displacement member 500 may be formed from a resilient or flexible material such that the displacement member 500 is transformable between a first configuration (
The processing chamber 440 of the container 432 has a processing volume in which foods are processed. In an embodiment, a portion of the displacement member 500 defines a boundary of this processing volume, such as an upper boundary of the processing volume when the container 432 is attached to a food processing base 22 for example. The contour of the displacement member 500 may be selected such that the processing volume when the displacement member 500 is in the second configuration is reduced relative to the processing volume when the displacement member 500 is in the first configuration. When in the second configuration, the displacement member 500 occupies a portion of the processing chamber 440. In the illustrated, non-limiting embodiment, the portion of the displacement member 500 that is received within the chamber 440, such as the portion that extends through the opening 437 of the second end 436 for example, has a concave contour. Accordingly, when the displacement member 500 is in the second configuration and occupies a portion of the processing chamber 440, the remaining portion of the processing chamber 440, such as extending between the first end 434 of the container 432 and the surface of the displacement member 500 facing the first end 434 for example, defines the reduced processing volume.
Further, the displacement member 500 may have a similar but opposite contour, such as a convex contour for example, when the displacement member 500 is in the first configuration. In such embodiments, such as where a portion of the displacement member 500 is arranged external to the processing chamber 440 when in the first configuration, the processing volume of the container 432 includes not only the volume of the processing chamber 440 but also the additional volume defined by the portion of the displacement member 440 arranged external to the processing chamber 440. However, embodiments where the processing volume is generally equal to or even slightly less than the volume of the processing chamber 440 and/or the container 432 when the displacement member 500 is in the first configuration are also contemplated herein. In such embodiments, the contour of the displacement member 500 in the first configuration need not be generally equal and opposite to the configuration of the displacement member 500 in the second configuration.
In an embodiment, the displacement member 500 is transformable from the first configuration to the second configuration in response to a manual input, such as application of a force to the displacement member 500 by a user. The force may be applied directly to a surface of the displacement member 500, such as to a portion of the displacement member 500 adjacent to, within, or overlapping the opening 437, or alternatively, may be applied indirectly to another component coupled to or associated with the displacement member 500.
During a food processing operation, at least a portion of the first agitating member 442 is rotated about its axis X to process, for example, chop, cut, dice, blend, or mix, the contents of the food processing chamber. During a food processing operation, the contents of the food processing chamber 440 may be propelled outwardly, towards the sidewalls 438 of the container 432 and may stick thereto. To facilitate the return of these particles of food stuck to the sidewall 438 to the first end 434 of the container 432, the displacement member 500 is transformed to the second configuration. By pushing the displacement member 500 into the interior of the container 432, the volume of the processing chamber 440 is reduced. As a result, the pressure within the processing chamber 440 is increased, thereby pushing the food downwardly towards the cutting assembly 442. In an embodiment, this increased pressure acts on and loosens the stuck food particles within the container 432. This transformation of the displacement member 500 from the first configuration to the second configuration may occur when the first agitating member 442 is operational, or alternatively, when the rotatable blade 446 of the first agitating member 442 is stationary, such as after a processing operation or during a pause of a processing operation.
In response to further processing, such as rotation of the cutting assembly 442 about its axis X, the heat and pressure within the processing chamber 440 will increase. Because of its resilient nature, the increased pressure within the processing chamber 440 acting on a surface of the displacement member 500 will cause the displacement member 500 to deform. In an embodiment, this pressure will move the displacement member 500 through the opening 437, to an exterior of the container 432. Accordingly, this increased pressure generated by operation of the first agitating member 442 will ultimately transform the displacement member 500 from the second configuration back to the first configuration. Although the displacement member 500 is not illustrated or described herein as including a second agitating member, it should be understood that embodiments where a second agitating member is arranged within the interior of the container 432 and operably coupled to the displacement member 500 are also contemplated herein.
